Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in more detail.
As shown in Figure 1, the all-hydraulic normotopia jumbo of a kind of automatic adjustment boring pressure and speed, comprise hydraulic system 2, electrical system 3, motor 4, underpan traveling system 5, operating desk control system 6, frame 7, principal arm assembly, forward beam assembly and hammer drill 8, frame 7 is arranged on underpan traveling system 5, frame 7 is made up of forebay and afer bay two parts, afer bay is provided with motor 4, hydraulic system 2, electrical system 3 and operating desk control system 6, motor 4, hydraulic system 2 are connected with operating desk control system 6 respectively with electrical system 3; Forebay is provided with principal arm assembly, forward beam assembly is arranged on principal arm assembly, and forward beam assembly comprises forward beam 9, and hammer drill 8 is arranged on forward beam 9, forward beam 9 is provided with automatic Regulation speed adjusting gear, and automatic Regulation speed adjusting gear is connected with hammer drill 8.
As shown in Fig. 2 (a), above-mentioned automatic Regulation speed adjusting gear comprises: wire rope 10, L-type support plate 11, pressure spring 13, look nut 12, circular cone inductor 14, noncontact inductive switch 16, pull bar 15 and propelling cylinder, L-type support plate 11 is fixed on forward beam 9, it is inner that propelling cylinder is arranged on forward beam 9, propelling cylinder is connected with the front supporting plate on forward beam, pull bar 15 is arranged on one side of L-type support plate 11, noncontact inductive switch 16 is arranged on the another side of L-type support plate 11, pull bar 15 one end connects look nut 12, the other end is by pinned connection wire rope 10, wire rope 10 one end connects hammer drill 8, the other end walks around pulley 1 cylinder lever connecting rod 15 front end on front supporting plate, pressure spring 13 is arranged on pull bar 15, between L-type support plate and look nut 12, circular cone inductor 14 is fixed on pull bar 15, and between L-type support plate 11 and wire rope 10, noncontact inductive switch is parallel with circular cone inductor 14 but do not contact, noncontact inductive switch 16 is electrically connected with the electromagnetic valve of propelling cylinder.
Above-mentioned forebay and afer bay two parts are articulated and connected.
Above-mentioned underpan traveling system 5 adopts fluid torque-converter mechanism.
After rock drilling operation starts, propelling cylinder drives the front supporting plate on forward beam 9 and pulley 1 to push ahead, thus drive wire rope 10, and drive hammer drill 8 to travel forward together, now, pressure spring 13 is compressed, just thrust is forward created to L-type support plate 11, the drilling rod of hammer drill 8 is pushed to scar, rock drilling operation formally starts, position as shown in Fig. 2 (a), when the speed of rock drilling boring and the pace comparison match of propelling cylinder, rock drilling operation just can be pushed ahead continuously, when running into rock stratum really up to the mark, cutting rate slows down, and propelling cylinder pace is high, just drive wire rope 10, pull bar 15, pressure spring 13, make pull bar 15 relatively L-type support plate 11 to have travelled forward a segment distance, pressure spring 13 is compressed to certain position simultaneously, position as Suo Shi Fig. 2 (b), at this moment noncontact inductive switch 16 and circular cone inductor 14 are responded to, noncontact inductive switch 16 is closed, thus the electromagnetic valve controlling propelling cylinder also cuts out, propelling cylinder fuel cut-off, no longer promote, and now hammer drill 8 under the promotion of pressure spring 13 elastic force, rock drilling operation proceeds, when hammer drill 8 is in the process of working on, L-type support plate 11 also constantly slowly travels forward under the promotion of pressure spring 13, when noncontact inductive switch 16 is no longer responded to as Suo Shi Fig. 2 (c) with circular cone inductor 14, noncontact inductive switch 16 is separated from circular cone inductor 14 and opens again, the electromagnetic valve of propelling cylinder is opened again, propelling cylinder starts fuel feeding, and a new circulation starts again, forms a pulse rock drilling process.
Pressure spring 13 in this mechanism, before hammer drill 8 operation, to be adjusted by look nut 12 according to the soft or hard situation of rock stratum, pressure spring 13 pairs of L-type support plates 11 are made to produce a precompression, incompetent bed precompression should be turned down a little, because the thrust that it needs is little, hard formation then will be heightened a little, because turned down, pulse frequency is too low and thrust inadequate and affect cutting rate.
Pressure spring 13 in this mechanism and wire rope 10 can also play cushioning effect, absorb a part of vibration force, protection drilling tool.
Underpan traveling system 5 adopts fluid torque-converter mechanism, and carry-over moment is large, and drives before and after adopting, and climbing capacity is strong; Forebay and afer bay two parts are articulated and connected, and turning radius is little, and jumbo is moved flexibly.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the utility model by submitted to claims determination scope of patent protection.
